Development Life-Span Human Development From Conception to Death
Prenatal Development Stage 1 = Zygote (the fertilized egg) 2 week period of rapid cell division (undifferentiated) Ends with implantation to uterine wall Over half do not successfully implant
Prenatal Development Stage 2 = Embryo human organism from 2 weeks through 8 weeks Begins with implantation to the uterine wall Placenta and major organs form, heart beats, liver makes red blood cells
Prenatal Development Stage 3 = Fetus human organism from 8 weeks after conception to birth rapid growth of brain and body in final 3 months
Prenatal Development Nature AND nurture matter in utero Critical periods (nurture) – particular stages of development when certain environmental influences have the most impact Teratogen - any factor (e.g., chemicals, viruses) that can reach the embryo or fetus and cause a birth defect Nicotine – low birth weight, learning disabilities Marijuana – irritability, nervousness, tremors Cocaine – respiratory problems, learning disabilities, seizures
Prenatal Development Fetal Alcohol Syndrome (FAS) physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking (five drinks per day) symptoms include facial misproportions, mental retardation, behavior problems
Critical Period:ThalidomidePoor Nutrition (e.g., protein deficiency)
Nature vs. Nurture Nature Genetics Nurture Experience Environment Learning Heritability
Conception and Twins Monozygotic twins – (identical twins) one zygote splits into two separate but identical masses of cells each develops into a separate embryo. Dizygotic twins – (fraternal twins) two eggs are separately fertilized by different sperm each develops into a separate zygote, then a separate embryo.
